rlhis invention relates to book-binding machines, and has particular reference to a, machine of this character Jfor binding volumes ot' varying dimensions.

An object of the present invention is the provision of such a machine, having means for forming semi-ilexible backs tor volumes fromA av single strip ot material.

A further object ot the invention is the provision of mechanism, whereby! a single piece of back material may be scored and formed into shape and; size to tit a particular volume under construction.

Another obj ectof the invention is the provision ot a book-binding machine, having means tor receiving a strip of back material, properly gaging it with reference to the matter to be bound, scoring said strip, sha-p ing and retaining-ie in proper'positionupon the matter to be bound, and drilling the complete volume preparatory to the inscrtion ot bindingelement-s;

Referring to the drawings in detail,y the numeral 10 designates base members or supports upon which the machine is mounted. Rig-idly secured to these base members 10 are n. pair ou" vertically arranged parallel Y the passage of the guide rods 111. The bars 16 extend in advance of the guide rods 11, and are connected at their forward ends by an angle bar 17. rPhe carriage 115v further comprises a table18, arranged rearward-,ly of the rods 11. An evener board 19 is adjustably mounted upon the table 18A and maybe shifted laterally thereof to accommodate the work thereon, it being providedwith a set screw 19. The top member 18 may be bolted or otherwise attached tothe bars 16, as shown. A bindinggage 20 is mounted upon the table 18 and is adapted to partake of vertical swinging movement upon a rod 21, which is in turn carried by a bracket- 22 having upturned ends 23 forming-bearings for said rod 21. rllhis gage 2O normally lies flat upon the table top 18, and may be shifted longitudinally thereof upon the rod 21, and retained in an desired; position by a locking ring 24 provic Yed with a set screw 25. The carri-age 15 further comprises a pair of cylindrical verticalsupporting ro`ds`2f'o', connected at their upper ends by a bar 27 having upturnedy ends 28. The rods 2G are positioned in advance of the guide rods 11, and pass tl'irough the upper tace of the angle bar 17. A leali supporting plate 30 is hingedly connected to a plate 30, which is in turn bolted` or otherwise attached to, the upper face oi? the angle bar 17, as shown. As'clearly shown, the leat supporting platel 30 projects beyond the forward edge of the angle bar 17, and" its outer edge is formed with a. plurality ot' regular shaped notches 31, which are equidistantly spaced, for apu-rpose to be described.

The numeral 32 designates a vertically reciprocatory pressure bar, for compressing and retaining the work to be bound upon the table 18. This pressure bar.32 comprises an angle bar arranged in parallel rela.- tion with the angle oar 17. *.Ihe a'igle har 33 has, bolted or otherwise secured tl'iereto, plates 34 and 35 corresponding to the lower plates 30 and 30, the plate 35 being identical with the plate 39 as concerns the notches therein, the notches 36 in plate 35 corre spending in size and number to theY notches 31 in plate 30 and being arranged in alignment therewith. The plate 34 projects slightly beyond the front edge of the angle bar 33, and is beveled downwardly as illustrated at 37.- This beveled plate 34 co-ac'ts with a shaping bar 38 pivotally mounted as at 38 for horizontal swinging movement in a block 39, as clearly illustrated in Fig. 3. The shaping bar 33 L-shaped in cross seetion, and has its horizontal face 40 notched as at 40', such notches corresponding in sin shape and number with notches 31 and .in the plates 3() and 35 and registering therewith. The shaping bar 38 normally lies over and in parallel relation te the plates 30 and 35, and is held in this position by a latch screw 41. The means for elevating the pressure bar 32 comprises a pair of revolvable screws 42 having screw-tlireaoed engagement at theirlower ends in stationary blocks v43 rigidly secured to the angle bar 33. The upper ends of the screws 42 are journaled in the cross bar 27 and carry beveled pinions 44, which in turn mesh with beveled pinions 45 fixed upon a horiaontal shaft 46, The shaft 46 is journaled in the upturned ends 2S of connecting bar 27, and carries upon one end thereof outwardly of the framewor".7 of the machine, a hand wheel 47, having a hand crank 48 whereby the shaft 46 and associated elements may be rotated. It is therefore obvious that rotation of the shaft 46 will result in the rotation of the screws 42 through the medium of the pinions 44 and 45, thus elevating or lowering the pref'- sure bar 32, dependent upon the rotation el. the hand wheel 47. Rigidly secured to the pressure bar 32 at a point beneath the block 39, and extending at a right angle with respect to such bar 32, a cam plate 49, whose cam face 50 is adapted to engage with, and

' limit the forward swinging movement of, a

scoring bar 79 to be hereinafter described. The cam plate 49 partakes of vertical movement with the pressure bar 32, the bevel face of the said cam pla-te providing a stop or rest designed to engage the carriage carrying the scoring bar, thus determir.' the limit of forward movement of the scoring bar 79.

Means are provided to move the carriage 15 and associated elements downwardly upon the guide rods l1 comprising a pair of upper links 51 and 52, and a pair of lower links 53 and 54. These linksare pivotally connected together as shown at 55 and 56. The links 51 and 52 are pivoted upon blocks 57, in turnrigidly attached to the rods 26. The links 53 and 54 have their lower ends pivotally connected with the base members l() as meme? shown at 58. The upper ends of the links 5 1 and 52 are connected by means ef a hand bar 59. Normally the carriage 15 is held against movement in the elevated position by reason of the links 51, 52, and 54 lying in the forward past-center position, and. coming to rest upon the bar 27. ,Vhen it is desired to lowerthe carriage 15, as is necessary in the operation of drilling a volume, the operator grasps the hand bar 59 and` brings it forward, thereby swinging the several links upon their pivots and causing them to move to a rearward past-center position, and a continued forward movement of the hand bar 59 will result in `the lowering of the carriage 15, due lo the leverage imparted to it by the connections of the links 55 and 56. Any sudden tlowering of the carriage 15 prevented and retarded by the application of retractile coil springs 69, connected at their lower ends to plates 6i aiiixed to the carriage 15, and at their upper ends to the connecting rod12. The springs 60 also tend to elevate the carriage 15 to its normal position, upon the release of pressure on the hand bar 59.

'The' numeral 62 de signates a drive shaft for a drill 70 employed in the binding operation. This shaft 62 is driven by any suitable means, such 4as an electric motor 63 mounted upon a suitable support carried by rods 64, in turn rigidly attached to the base memberl 10 as shown. As shown, the motor support may be adjustably mounted upon the rods 64. The numeral 65 designates a gear housing adapted to receive and house gears 66 and 67. The gear 66 is mounted upon the drive shaft 62, and may partake of sliding movement thereon. The gear 67 is aflixed to a vertical shaft 63, carrying at its upper end outwardly of the top of the house partake of reciprocatory movement upon the rods 13 and 14 and the drive shaft 62, and may be locked in any predetermined position by a latch element 71, having a pin 72 for engaging in any one of a series of depressions 73 formed in the rod 13. The latch 71 is pivotally mounted within the housing 65, as at 74, in such manner that its greatest weight is upon one side of the pivot 74, whereby such weight will always tend to engage the p in 72 within one of the depressions 73 when the drill is in proper position for operation. It might be stated at this point that the positions of the depressions 73 are such, that when the housing 65 is locked in any one depression the drill 70 will lie centrally of a corresponding series of notches 31, 36 and 40, thus when the carriage 15 is lowered with a volume in place the drill 70 will pass through the notches and through the matter being bound. The drill 70 may be shifted Leaves? along the rods 13 and 14 to varying posi-l tions, in order to enable the drilling of a plurality of holes in theA volume.v Whenever it is desired to shift the drill 70, it is first necessary to= elevate the carriage 15.

Means have been provided for scoring the material designed to form the back and covers for the volume, which material is comprised of a single strip. The scoring mechanism is indicated as a whol-eby the numeral 75, and comprises vertically swinging support arms 76 and 77, pivotally supported at their lower ends upon the rod 18, but contacting with the base members 10 to prevent any longitudinal movement on the rod 13. Rigidly attached to the arms 76 and 77 adjacent their upper ends is a horizontal diel bar 78, arranged in parallelism with the angle bar 17, and having its top edge lying 1 1ny approximately the same horizontal plane with the top. of the table 18. A. co-acting die bar 79 is arranged above, and in parallel spaced relation with, the bar 78, and coacts therewith. for scoring the back material therebetween. The die bar 79 is hingedly connected, as at 80,. to side plates 80 carriedfv by the arm. 7.6, whereby the bar 79 may be swung in a vertical plane to permit of the insertion of material to be scored. A handle81 is formed uponv the bar 79 to facilitate they operation thereof. As clearly shown in Figs. and 6, the die bar 78 is provided; with chan-nels 82 'adjacent its outer edges and in its upper face. The formation of these channels 82 leaves a central portion in the form of a rib 83, which extends for the entire length of the bar 78. It will be observed that the bar 79 is provided upon itsl lower contacting face with a channel 84, also extending for the entire length of the bar 79. The formation of this channel 84 provides a: pair of ribs 85, which in their normal posi-tion lie within the channels 82 but spaced fromV theA sides and bottom thereof?, at which time the rib 88 will lie` within the channel 84 a corresponding depth, the

`channels in both bars being of the same depth. As illustrated in F ig, 7, the lower bar 7 8 is provided with: an upstanding lug 86, formed upon the rib 88. The purpose of this lug 86 is to properly space the bars 78fand 79, iny order to effect the proper scoring of the blanks and to avoid cutting the material being scored. This spacing is the same throughout the entire length ofV the bars, as shown in Fig. 7, the upper bar 79 having its lower face slightly rounded, as at 87, to permit of its being swung upwardly without binding. The arm 77 is provided with a pair of guide plates, bolted or otherwise secured to its edges upon opposite sides of the bars, as shown at 88, and these plates 88 project above the top` ofthe upper bar 79 and diverge slightly, to facilitate the entry of the bar 79therel-xetween. The plates `nism 75.

88 are wider than the thickness of. the arm 77, and project slightly therebeyond, A laterally swinging latch member 89 is pivoted at 9O1to the carriage 15, and is provided with a pair of notches 91-adapted toy enga-ge over the edge of' the plates 88. to positively hold the scoring mechanism 75 a predetermined position during the initial binding opera-tion. The scoring is accomplished by raising the bar 79, placing the material to be scored between said bar 79 and the bar 78, and then bringing the bar 79 down with sufficient pressure to force the material into the several channels, whereby said material will assume a shape as illustrated in Fig. 6. i 1f so'desired, a conventional form of trimming knife may be embodied in this machine, to enable an operator to carry out upon a. single machine all the steps of binding. This trimming mechanism embodies the usual gaging or trimming board 92,A having ametallic stationary knife 98 affixed thereto. This knife is adapted to .co-act with a vertically swinging knife 94, pivoted in a fixed bracket or bearing 95 carried by the board 92. The bracket 95 is provided Vwith a cam face adapted. to be engaged by a lug 96 carried. by `the head of the knife 94, and this lug 96 is heldin engagement with the cam face during the travel. of the knife 94, by a spring 97 surrounding the pivot pin ofthe knife 94. In this manner the swinging knife 94 is always retained in proper cutting Yrelation with the fixed. knife 98. An operati-ng handle 98` is formed upon the swinging knife 94 to facilitate the operation thereof. As illustrated, the board 92 may be supported upon a pair` of rods. 99, affixed to the base by means of blocks 100 havingy suitable set screws 100.

Means are employed to veounterbalance the swinging movement of the scoring mechanism 75 toward and away from the binding table 15, comprising a weight 101 affixed by a set screw 101 to an. offset lever 102. This leverv 102 in turn pivotal'ly attached to the face of thearm 77, as. shown atv103, and in such position, relative tothe lower ends of the plates 88, that when the scoring mechanism 75 is swung to the position shown in Fig. 1, downward-swinging movement of the lever 102 and weight- 101 will be limited by the abutment of the lever 102 against the lower ends of the plates 88. lVhen the mechanism is in this position, the. weight of the scoring mechanism 75 will overbalance that of the weight 101, and will remain in this position until the scoring mechanism 75 is elevated sufiiciently by the operator to enable the weight 101 to overbalance the weight of the scoring mechal/Vhen the scoringmeehanism is swung. outwardly, the movement is limited by the abutment of the weight 101 against the head of the pivot 56. l

Assuming that the parts are in the position illustrated in Figfl, the operation of the machine is as follows:

The hand wheel t7 is rotated to cause the pressure bar 32 to be elevated. A sheet of paper the size of that to be bound is placed upon the table i8, its forward edge lying exactly even with the outer edge of the plate 30. This operation is to cnablethe operator to properly gage the scoring of the back material. The plate is then raised, and moved over' the'sheet of paper so that its rear edge will be even with the rear edge of the pap r, as shown .in Fig. The gage 2O is then set in this position by the locking collar 24 and we are now ready to make the scoring of the haelt.

The scoring mechanism 7 5 is then swung upwardly to the pos ion shown in Figs. 2, 3, 4t and 5, and the latch 89 is swung into engagement with the plates 8S. The scoring mechanism 7 5 is now locked in position for the initial. scoring. The die bar 79 is next swung upwardly and a strip of back material is inserted between the die bars 78 and 79 and beneath the pressure bar 32, l over the paper already in the machine. end of the baclr material is inserted a suficient distance, so that end will abut the forward edffe of the 20, and when in this position the pressure bar is loue ered and bonds the material lirmly in place The die bar 79 is then brought 'lorcibiy down, for giving the initial scoring to the material. It might be noted this point, that when the scoring mechanism 75 is in the locked position, the distance between the outer score line (indicated at A in Fig. 6) and the inner edge of the back material (indicated at B), is sufficient to completely receive the sli-.cet of paper with a. margin c11- tending therebeyond, as clearly shown. The next scoring operation will be gagged by the thickness of the volume under construction.

The pressure bar 32 is now elevated. and the latch S9 swung outwardly. The die bar 7 9 is elevated, and the cover' material inserted under the pressure bar 2li/J until ond l); is even with the rear edge of the gage 20. The leaves to be bound are then placed evenly upon the back material so that their forward edges are even with the score line A,'at which time the pressure bar '32 is lowered andv lirmly clamps the volume upon the table 18, with thefrec end of the bach matcrial extending between the scoring bars 7S and 79. The position of these scoring bars with respect to the carriage l5 is now determined by the position of the cam plate 49, it being remembered that this cam plate moves upwardly with the 1L' essure bar 32. Thus, in the position illustrated in Fig. 6, the pressure bar 32 has been elevated in accordance with the thickness of the volume and, as shown, the cam plate #i9 has been elevated a corresponding distance, and has engaged. and moved the scoring bar 7 9 outwardly to a position forwardly of the car-v G. The shaping bar 38 is then swung .intov normal po.. .ion over the folded back por tion and is locked in this position by the latch 41.

The back now been formed, and the volume is ready to be drilled. The drill mechanism is moved along the rods 13 and 'llt until the drill 70 is in position at a point beneath the volume. The operator then grasps the ha.=.d bar 59and swings it forward, which movement lowers the carriage l5 and assmciated elements, this action resulting in the passage of the drill through the notches 3l, 36 and 40, and obviously through the volume. The operator may then piace suitable binding fasteners through the openings, pressing lthem firmly into place by hand. The volume may then be released by the outward swinging of the 'shaping bar 3S and the subsequent elevating of the pressure bar 82. The volume may then be placed upon the table 18, with its bound head under the pressure bar 32. Lowcrine; of the pressure bar 32 at this point will result-in the binding elements being firmly forced into place. I contemplate employing fasteners of the type illustrated in Fig. 9. for which l have secured United States Letters Patent. Any projecting edges of the volume may be conveniently removed by the trimining` mechanism shown.

It will be obvious from the foregoing that an extremely simple machine has been provided for carrying out the complete details involved in the binding` operation. The device as a whole is compact, requiring a minimum of space `in theshop, and is of such size to be portable if desired. The machine carries out each operation, from the gaging of the bach material for the scoring, to the final drilling, binding and trimming.

lt is to be understood that the invention is not limited to the precise construction set forth, but that it includes within its purview whatever changes fairly come within either the terms or the spirit of the appended claims.
